How do I pipe the output of uptime/df to curl?

  • 772

I want to send the output of uptime and df commands to a web app using cURL. I tried: 

uptime | curl http://someurl.com -T -

But that didn't seem to send the data.

What is the proper way to send the output of a command to cURL as a POST parameter? (or wget if that's much easier)

linux pipe curl wget

  1. You can use the -d option in curl with a @- argument to accept input from a pipe. You will need to construct the key-value pairs yourself. Try this:

    echo "time=`uptime`" | curl -d @- http://URL

    The backticks (`) denote that the enclosed command (in this case uptime) should be executed, and the backtick-quoted text replaced with the output of the executed command.
